How can international artist participate in art fairs in the United States?

Hello everybody

I'm a Colombian artist, all the traveling I love doing make me a bit international.

Many people like my art in North America, is why I would like to participate in art fairs there.

Could someone please give me information about what is needed for foreigners to sell art in art festivals in the United States? Or information about international art festivals in general.

It will be greatly appreciated.

Natitota :)
